Description
Technical Field

Background
The chalcogenide glass is a medium-long wave infrared optical material with excellent performance, and is widely applied to the production fields of infrared lenses, thermal imaging lenses and the like. But in chalcogenide glasses such as H 2 O, hydroxyl and other impurities can seriously affect the infrared transmittance of chalcogenide glass, so that lens materials with strict requirements on transmittance and transmittance wave band generally need to be purified in the preparation process of raw materials with relatively low purity. Due to chalcogenides in large partThe method has the characteristics of high saturated vapor pressure and easy sublimation and gasification, so that the chalcogenide glass can be purified by utilizing the characteristic of large difference between the saturated vapor pressure of the chalcogenide compound and the saturated vapor pressure of impurities and oxides. In addition, the processing leftover materials and defective products with corresponding proportions can be produced in the processes of cold processing and mould pressing processing of the lens materials, and the leftover materials can be purified and recovered by adopting a distillation purification method, so that the resources are effectively saved, and the production cost is reduced.
The method is characterized in that an H-shaped quartz ampoule bottle is generally used for carrying out distillation purification on chalcogenide glass raw materials and leftover materials, raw material filling is carried out on one side of the H-shaped quartz tube, the distillation purification on the raw materials or the leftover materials is realized by controlling the temperature difference between the two tubes, and the chalcogen element has higher vapor pressure at a relatively low temperature, so that the high-temperature process of the quartz ampoule bottle during distillation is relatively mild. Therefore, after distillation and purification are completed, the Cheng Liaoguan of the original H-shaped quartz tube still has excellent thermal and mechanical properties, and if the recycling of the quartz tube on the material containing side can be realized, the use of the quartz tube in the preparation process of chalcogenide glass can be reduced, so that the purposes of resource saving and cost saving are achieved.

Detailed Description
The method for recycling the quartz tube according to the present application will be described in detail below.
The application discloses a recycling method of a quartz tube, which comprises the following steps: cutting off a quartz tube along a vapor transmission tube, and treating a fracture; step two, placing the treated quartz tube in sodium hydroxide solution for soaking, and keeping the temperature of alkali liquor at 80-100 ℃ in the soaking process; taking out the quartz tube after the soaking is finished, using pure water to wash out alkali liquor attached to the surface of the quartz tube, transferring the alkali liquor to aqua regia for soaking for 1-2 h, then using the pure water to spray the outer wall of the quartz tube, then pouring two thirds of pure water into the quartz tube, shaking the bottle body for 8-10 times, then draining washing water in the bottle, and repeatedly cleaning for 3-5 times until residual water at the inner side of the bottle forms a film-shaped water film to uniformly flow down; step four, using the pure water spray pipe body for 2-3 min, drying, and taking the pure water spray pipe body as required in the use process; and fifthly, the quartz tube can be used for melting the chalcogenide glass bar stock by using high-purity raw materials.
